How to Play MultipleAudioTrack in Roku?

I know about Roku doesn't support multiple videos at a time. But Some Developers are mix up two things multiple playbacks and multiple audio tracks. Roku Does Support Multiple Audio Track?

I tried to Play MultipleAudioTrack in Roku. I used the below code to find a multiple audio track Here ?"m.video.availableAudioTracks :"m.video.availableAudioTracks but here not available any track. my stream check-in VLC MediaPlayer. Here two-track available. But I not found in Roku. My Audio Format is AAC. I also Set Here m.video.audioFormat = "aac". Any other Configuration required to Playing a multiple Audio.

My m3u8 file is below.

#EXTM3U

#EXT-X-TARGETDURATION:9

#EXT-X-MEDIA-SEQUENCE:1

#EXT-X-VERSION:3

#EXTINF:8,

RokuMedia00000001.ts

#EXTINF:8,

RokuMedia00000002.ts

#EXTINF:8,

RokuMedia00000003.ts

Is there any Configuration required for m3u8 file.

I read the HLS Documentation which is provided by Roku. But, If you don't mind I have still some doubts regarding HLS Stream. I used the Roku Premiere plus device.

But, I'm not required to enable multiple audio tracks at the same time. or also not required to playing simultaneously. I required to at a time only a single audio track. Because I know any media player not support multiple audio track and video track same timesI required to change the audio track at run time. If my default track in English and using this option, I change to It Spanish or any else.

My Actual question is a how-to enable audio track option which provide by Roku and which fields are required in m3u8 files. To enable these options. or Roku has stopped supporting audiotrack options?
